VSPECIIFICAJLIOAT forming part of Letters Patent No. 527,025, datedOctober 2, 1894.v Application nea December 1, 189s. serial No. 492.431.(No modelf .To all whom it may ,concern/i Be it known that we, CARLSOHRAUB- sTADTER, Jr., j and CHARLES R. SGHILLING., both of the city ofSt. Louis, in the State of Missouri, have invented a certain new anduseful Improvement in Routing-Machines, of which the following is afull, clear, andexact description, reference being had to theaccompanying drawings, forming partof this specification. Y

Our invention relates to certain improvements in the constructionofmachines for routing printing blocks, and the like; and our Inventionconsists in features of novelty hereinafter fully described and pointedont'in the claims. I

Figure I is a side elevation, illustrative of our improved machine. Fig.II is a top view. Fig. III is a front, end view or elevation. IV is anenlarged, vertical section of the spin- 'dle, with its support. Figs.Vand VI are enlarged, detail views, illustrating fthe manner ofautomatically lifting the gage. Fig. VII is a detail view, showing thegage raised. Fig. VIII is an enlarged view of the rock-shaft, with itscranks or arms. Fig. IX is an enlarged, detail view, showing the mannerof mounting the swinging arm on its support.

Referring to the drawings, l represents the frame of the machine, havinga top 2with rails or slides 3 upon which the table 1l moves.

5 represents ahub form ed on top of the machine and which is adapted toreceive a vertical shaft 6.

perforation 9 from the projections 10, so that the operator can move theouter end of the lever toward orfrom him, by raising it so as todisengage it from the notch or projections of the head 1l, and then bylowering it again the slot 9 receives the desired projection 10, andthus the operator is enabled to move the Fig.

The table is moved throughv means of an arm 7, on the shaft 6, and con`means of journal boxesv 29.

lever back and forth with relation to the arm 7, as may befound by himthe most convenient position for'the lever.

l12 is an arm mounted on a stem 13, projecting upwardly from the top ofthe machine. The manner of mounting the arm on the stem is shown inFig.`IX, and consists in slipping a box 14 over the stem which isstraddled by the bifurcated end 15 of the arm, and to which `TO THEWESTERN GRAVERS SUPPLY COMPANY,

tho arm is held by conically pointed set screws 16. By thus Ymountingthe arm, its forward end can be swung either in a horizontal or verticaldirection, as will be readily understood.

17 is a spindle which carries the routing tool 18, held to the spindleby a suitable form of chuck 19.

v 2O represents' blades set at an angle on the outer/surface of thechuck 19, and which produce a current of air suicient to remove theportions of the printing block cut by the tool.

21 represents a sleeve or bushing fitting between the spindle 17 and thearm 12, and

above which is a pulley 22, having a pin or ,other connection 23 withthe spindle. The

sleeve orbushing 2l is capable of being moved i vertically in the arm12, to feed the tool, and it is thusmoved by a screw 24. passing througha projection 25 on the sleeve or bushing, and which screws into theupper surface of the arm 12.

The belt that drives the tool passes from the motor power, over pulleys26, journaled onthe inner end of the arm -12, and around the pulley 22.

y The arm 12 has a hand-hold 27, by which it is swung or moved in itshorizontal direction. 28 represents a rock-shaft secured'to the underside ofthe top 2 of the machine, by On each end of this rock is an armor crank 30. (See Fig. VIII.) Under the forward end of the arm 12 is across-head ory bar 3l, from which projects vertical rods 32, which passthrough sleeves orkboXes 33 secured to the top 2 of the frame of themachine; the rods being preferably reduced in size where they passthroughthe boxes so as to form shoulders 34 tolimit the downwardmovement of the rods 32, and consequently the downward movement of theinner end of the arm 12. To the lower end of the rods 32 the arms orcranks 30 are secured as shown at 34, Fig. I.

Projecting from near the central portion of the rock shaft 28 is an arm35 connected by a rod 36 to a foot-treadle 37, and projecting also fromthe rock shaft 28 is an arm 38, from which projects a rod 39, (seedotted lines, Fig. 1,) which is surrounded by au expansion spring 40. Todepress the inner end of the arm 12, pressure is applied to the treadle37, and when the pressure is removed from the treadle, the spring 40restores the arm l2 to its normal position.

41 represents a gage for use in certain classes of work, and which ispivoted to the top 2 of the machine by a rod 42.

43 is a spring for holding the gage normally in its lower position uponthe table.

44 is a cam secured to one of the rods 32 by means of a screw 45. Whenthis cam is raised into the position shown in Fig. I, it will pass overthe gage 4l, but by lowering the cam the gage, in the backward movementof the table 4, engages the cam, causing the gage to be raised, as shownin Figs. VI and VII, so that when it is desired,the gage can beautomatii call y lif ted or raised, as the table recedes, and held 1uthis supported position by the cam so long as the table is not movedforward sui- 3o ciently far to carry the gage beyond the cam.

The object in raising the gage is to get it out of the way of lthe tooland of the operator so as not. to interfere with the operators View ofthe work while routing.

We claim as our inventionl. In a routing machine, the combination of themovable table, a gage hinged to thetable, and a stationary cam forautomatically lifting the gage, substantially as set forth.

2. In a routing machine, the combination of an arm, a cross head or baron which the arm rests, vertical rods extending from the cross-head, acam secured to one of said rods, a movable table and a gage pivoted tothe table, and adapted to be automatically lifted by said cams;substantially as and for the purpose set forth.

3. In a routing machine, the combination of a table, a gage hinged tothe table, and an adjustable cam 44, substantially as and for thepurpose set forth.
